Ansar Al-Sunna, the group who beheaded and killed 12 Nepalese are the extreme terorists who came into existance only few years ago. The fight for recognition between different terrorist groups has caused vigorous comeptition amongst them to be gruesome. Ansar Al-Sunna has never negotiated and has killed including deputy prime-minister of Iraq in the past. These Nepalese unluckily were in the hands of these gruesome terrorists and had their fate. They seem to understand even before that they were going to be killed. On the video, most of them said that this was going to be the last time they were wishing to the family. I doubt if anything could have been done by the Nepali government to stop this.
